Question

4 ties and 7 shirts cost $746 . A shirt cost $50 more than a tie . What is the cost of the tie ?

Answer 1

let ties be t, let shirts be s.
4t+7s=746$
1s=50$
7s=50*7=350
4t+350=746
4t=746-350
4t=396
t=396/4
t=99$
A tie cost 99$

Answer 2

Efa needs to learn that the dollar sign ($) goes BEFORE the number, not after.

$746
$50
$99
etc.

If Efa is going to "help" others, he/she needs to get things right, even what seem like the little things.

Answer 3

easier way (and correct answer) :
let the cost of a tie be $x
cost of a shirt = $(x+50)

4x + 7(x+50) = 746
4x + 7x + 350 = 746
11x = 396
x = 36

Each tie costs $36, (and a shirt costs $86)

expensive tastes!

Answer 4

Wow ... it looks as if Efa needs to stop "helping" other students. =(
